1 Claim. (01. 257-137) This invention relates to an automotive vehi- 66 of Fig. 3, parts being broken away to show cle heater adapted to introduce fresh air into the the construction of the centrifugal fan, most of passenger compartment of motor vehicles, but the conduit being omitted; Fig. '7 is a view simialso useful for other analogous situations. lar to Fig. 5 showing a modification of the ple- 5 The principal object of this invention is to pronum chamber; and Fig. Bis a fragmentary sec- 5 vide a device which is capable of heating fresh tional view on the line 8-8 of Fig. 7.

The cowl 6 supports the not had sufficient capacity to heat fresh air inwindshield 1 and is provided with the customary troduced into passenger compartments of vehiowl Ventilator openin 8 having a cover to the passengers and it is an object of this deinlet and outlet pipes l0 and held in place by any vice to deliver to the heater a sufiicient quantity convenient means, in this case washers and lock of fresh air to insure the most comfort to the nuts being used, is the heating unit generally passengers and at the same time recirculate the indicated by the numeral II. It is understood body of air already in the passenger compartthat any convenient and suitable means of sup- 20 ment so as to insure aconstantly moving body porting the heating unit may be employed. of air properly heated, to a comfortable degree Communicating with the heater II is a fresh air and mixed with a constant stream of preheated conduit indicated generally by the numeral l2.

In Fig. 2 he uct leads o an adapter novelmeans for circulating and recirculating s which is co ct to the plenum chamber the air introduced into the passenger compartit which is, as described above, adjacent the face ment and already in the compartment in relation of the radiator I! of the heater II. The duct in and economical device is provided for securing of the vehicle and is provided with a filter 20 the above object, nd one wh h. ill not get out and adrain 2!. The vehicle engine is indicated of order. at'22 and has a cooling fan 24 suitably attached.

With these and other more limited objects in The plenum chamber It may be of any de- 40 view, the invention consists in various features sired shape either as shown in Fig. 5 or prefer- 40 of construction and combination of parts hereably as shown in Figs. 7 and 8, andis attached inafter described and illustrated in the accomto the housing 36 and is in communication therepar ying drawings in which Fig.1 is a diagramwith. The plenum chamber in Fig. 7 covers matirsview of a fragment of the motor vehicle that part of the radiator II .which is opposite with an air conditioning device according to the the sleeve element 44 on the opposit deof the 5 invention installed; Fig. 2 is a similar diagram radiator and an additional part of the radiator showing another means of supplying fresh air beyond the area covered by the sleeve 44. The and showing the same structure as Fig. 1 in plan; plenum chamber may extend in any direction Fig. 3 is a. central vertical section of the device from the center area opposite the sleeve 44 as shown in Fig. 1, the fresh air duct and most the purpo s of th plenum chamber is to p 50 of the vehicle being broken away; Fig. 4 is a vide-a source of fresh air to the centrifugal type section corresponding substantially to the line fan 41 'and the propeller type fan 53 and still 4-4 of Fig. 3; Fig. 5 is a section corresponding permit the propeller type fan 53 to draw air fromsubstantially to the line '5-5 of Fig. 3; Fig. 6 is the passenger compartment for re-circulation.

55 a "section corresponding substantially to the line It is obvious in both of the embodiments, Figs. 55

1 and 2, that the motion of the car wfll tend to create pressure forcing air through the ducts I! to the heater II and that undesirable moisture is eliminated before the fresh air can reach the heater II and that filtering means l5 or 26 prevent the ingress of foreign material such as dust to the passenger compartment. It will be noted that thermostatic elements 3| are interposed between the plenum chamber IG and the air duct l2, or as shown in Fig. 2, they may be placed in the adaptor l8. The thermostatic device operates a closure 32 shown in Fig. 3 which when in with a radiator I! which is equipped, with water. headers of the usual type through which hot water is circulated by means of inlet and outlet pipes I0. Adjacent one face of the radiator. I! is the plenum chamber 16 which covers the center portion of the radiator and an additional portion as shown in Figs. '7 and 8. The radiator is carried by the outer shell ,38 of the heater. Within the outer shell 35 and carried by brackets 38a is a housing element 38 which supports a motor 39 by means of carrying elements 40 which may be of any suitable construction.- The housing 38 entirely surrounds the motor 3! and has a central opening. which opens toward the radiator H. The motor 39 which may be driven either by air or electricity, has attached to its shaft 42 a fitting 43 carrying a cup shaped sleeve element 44 providedwith openings ll for the passage of air. Telescoped with the sleeve element 44 is a sheet metal flaring element 4 which carries the rotor 41 of a centrifugal type fan provided with vane elements 48. The motor shaft 42 and the elements ll, 46, "and 48 rotate as a unit. The sleeve element ll terminates adjacent the radiator I1 and opposite, or in register with, the plenum chamber It.- The housing 38 has a radial outlet 50 which communicates with a fitting ll which carries valve control means I! which may be so constructed as to permit delivery of air to the various outlets.

Supported on the sleeve element 44 is a propeller type fan 53 preferably comprising a sheet metal flange 54 and blades II.

It will now be seen that when the motor ll is running, the air will be drawn by the rotor 41 operating in the housing 38 through the sleeve 44. This will cause the fresh air to be drawn from the plenum chamber II through the radiator l1 and the air will then be delivered by the centrifugal fan to the fitting ill and thence to any desired place depending upon the manipulation of the valve means 52. At the same time the propeller type fan I! will operate and draw air through the radiator Il, part of which air will be fresh air drawn from the plenum chamber I8 and part of which will be air from the passenger compartment for re-circulation as shown in Piss. 7 and 8. In the case of the device shown in the other figures the air will be drawn from the recirculated air in the passenger compartment only. The outer shell 36 is provided with a series of outlet louvers which will permit the air drawn in by the propeller type fan 53 to escape into the passenger compartment. The passenger compartment may be provided with an outlet to relieve the pressure in case the compartment is sufliciently air tight to render that precaution necessary.

It will be seen from the foregoing that I have described a device which is well adapted for its intended purpose and while I have shown the present preferred embodiments of the invention, it is understood that I am not limited to the details of the disclosure but only in accordance with the appended claim.

Having thus described my invention, what I claim is:

In an automobile heater, a radiator, a cen trifugal I an on one side of said radiator, a housing enclosing said centrifugal fan having an inlet adjacent one face of said radiator, and a radial outlet, a propeller fan located between the centrifugal fan and the radiator, a fresh air duct having an outlet adjacent the other side of said radiator opposite said centrifugal fan housing inlet and covering an additional portion of said radiator and a housing enclosing said propeller I fan, saidcentrifugal fan and said radiator.
